Hey guys im new to this dildo thing and i was thinking of going out and buying one of some male porn star although im not sure since ive never done anything through the arse so i wanted to ask what should i go out and buy if im looking to getting a dildo and what do you all recommend?

Like Chuck said, make sure you've emptied your bowels beforehand, otherwise it could get messy. As with all the other advice, start small. Try experimenting with fingers first, once you've opened your hole enough to get a couple of fingers in without discomfort, try the dildo. And something very important with dildoes is hygiene. Make sure you clean it very thoroughly after using it. Use a sensitive anti-septic cleaner. I personally would also always clean it before I use it, just to be sure.

My two cents!
I started off with the Ass Master (The Anal Pleasure System) (here http://www.versandstadel.de/shop2/sh...der/233_gr.jpg, which is a little thinner than my bfs cock), it was small, but bigger than just fingers. I had little trouble with this at all. You should start small and work your way up, and use LOTS of lube! You'll know when your ready for something of a larger size.
As for the "mess" issue, I've found those douche things can be very useful! (this is the one I have http://www.lovehoney.co.uk/product.cfm?id=952, that site is very good for price btw ).
I'd go up using plugs rather than dildos, the tapering shape will be good for you to get stretchier and more used to it in a more gentle fasion!

I agree with Nouveau about the butt plugs. That's actually what I use most often.

As for the douche, well... I wouldn't invest any money right now. Make sure you enjoy anal toys and you really need it. As long as I take a dump first, I just have a few little bits on the toy when I'm done. If that's just not clean enough for you, then yes - invest in a shower attachment or anal douche bulb. I've heard you can find the bulbs at Wal-Mart and most drug stores, but I got mine from an adult store.

The bulbs are much cheaper and easier to hide when your Aunt Prude drops by for Sunday brunch, but I've heard the shower attachments do a better job. I use a bulb when I'm planning to have sex, just in case.

This calls for a professional.........This may to graphic, so caution those of you reading past this point. It's just that there is so much more to it than sticking it in...

First off have you even explored this area? If not, then I suggest you get use to your fingers first. I am sure you have, as most of us have already experienced this during puberty. Best way to getting use to anal play is to be patient and enjoy all the sensations. Listen to what your body is telling you. If you are experiencing severe pain, then you need to stop. It should feel good and not make you squint your eyes. Go buy yourself a small dildo. By small, I mean something that is not larger than 1" in thickness. I would get something that has a good length to it. No...not what you think. That way you can have something to hold onto. I'm sure you will not be going for any depth this early in the game. Make sure you use plenty of lubrication. You can even put some on the inside, as this will help coat the inside of you ass. Then start off real slow with your insertion. Never ever shove the whole thing in at one time. That could cause damage to your outer ring. If you like the way it is feeling, then insert more. I would even suggest you pull it back out slowly. Then start over. This will get you use to the sensation of having that outer ring opened. Then before you know it, you will have inserted the head inside. It sometimes helps to pause once the head get inside. This will allow your body time to adjust to having something going in, rather than out. Then as you progress with your play. You will begin to learn the aspects of depth play. Just have fun, enjoy the sensations that ass play can give you.

BBB2.5 sure knows his stuff
One more thing, make sure you do listen to what your body is telling you. You'll know how much and how far you can go. With luck you will relax easily
(I found I enjoyed anal shinanigins very much so progressed very quickly 'up the scale' as it were because it was so enjoyable and I found it very easy to relax. As fot the douche, I have it for my boyfriends sake; I want to make sure I'm squeaky clean for him, lol. If you don't mind a little bit of mess, then don't bother with one.)
So yes, listen

always start off with something small...dont think you have to have the John Holmes one up you butt to start..i have always been a top..but a few years back the married man i would service 3-5 times a week finally said one day he wanted to take my virgin ass... so said soonand i went out and bought a good size dildo... i kept trying it every day..and would give up...it was too big and hurt like hell... then it was getting down to d-day and i had a few drinks and kept working on it.. I had 3 small dogs and they even ran when i started yelling and saying those 3 and 4 letter words... but i finally got it in there...then used it 2 hrs before he came over... this man bi/married and very hung and masc walked in with a hard on and first word was i want your ass... and i said okay..but let me direct it in at my speed... it still was a tough one...he was 9x2 in and 6" round..my dildo was 7" but also 7" around.. one he got passed what i call the "gate keeper" i pushed that mother in and kept going and yelled and talked nasty to this dude..he got his rocks off very fast.. shit..should have kept my mouth closed...it was starting to feel good.. but we did it a few more times before he moved... (darn)since i top ..i always find it better to use a small dildo on 95% of the bi/married men before i try to penatrate them... and then i can fuck them for over 60-90 mins.. i love long slow sex.. and most of them do also once the are used to it..

I don't mean to be repetitive but just take things slow and relax. Remember, its supposed to feel good. When I first started I had a butt plug that was really helpful at getting my ass used to things going up there. As for cleanliness, thats up to you. I'm a clean freak and usually do ass to mouth so I always have an enema beforehand. Hope this was helpful and have fun!
